What is the purpose of a crankcase vent filter?

A crankcase vent filter allows gases to escape from the engine crankcase while preventing dirt and debris from entering. This helps maintain proper pressure and prevents oil contamination. It's especially useful in racing or vintage car applications.

How do I clean and reuse the K&N vent filter?

You can clean the filter using K&N's filter cleaner and oil. Simply apply the cleaner, rinse with water, let it dry, and then re-oil the filter before reinstalling. This will help maintain its performance and extend its lifespan.

Does this vent filter come with any hardware for installation?

The K&N 62-1520 vent filter is designed to push in and clamp directly onto rubber or plastic tubing. You may need a clamp to secure it in place, but no other hardware is included.
